This is a great place to stay when you visit Bangkok. The location is very good, easy to find, near Ratchathewi BTS station and bus station. You can also walk to some interesting places such as Bangkok Art and Cutural Centre (free entry) or Phetchaburi Soi 5 - one of the best Bangkok street food streets.
The host is very kind and helpful (when we asked a big box for check-in baggage, he helped us buy it). 6days7nights also provides water, milk, tea...for free (you just need to self-service).
We spent 5 nights in Cruising room and we were all satisfied. The room is decorated with specific theme, clean and comfortable (I love the fragrance of lavender in the room).
